A modular, extendible and field-tolerant multichannel vector magnetometer based on current sensor SQUIDs
Jan-Hendrik Storm, Dietmar Drung, Martin Burghoff +1
We present the prototype module of our extendible and robust multichannel SQUID magnetometer system. A multi-module arrangement can be implemented by using up to 7 modules. It is i…
An ultra-sensitive and wideband magnetometer based on a superconducting quantum interference device
Jan-Hendrik Storm, Peter Hömmen, Dietmar Drung +1
The magnetic field noise in superconducting quantum interference devices (SQUIDs) used for biomagnetic research such as magnetoencephalography or ultra-low-field nuclear magnetic r…
Improved Calibration of Instruments for Small Direct Currents
Hansjörg Scherer, Dietmar Drung, Christian Krause
We report on new calibration methods for picoammeters and low-current sources. The "Ultrastable Low-noise Current Amplifier" (ULCA) was used for the exemplary calibration of commer…
A nuclear magnetic resonance spectrometer for operation around 1 MHz with a sub 10 mK noise temperature based on a two stage dc SQUID
L. V. Levitin, R. G. Bennett, A. Casey +5
We have developed a nuclear magnetic resonance spectrometer with a series tuned input circuit for measurements on samples at millikelvin temperatures based on an integrated two-sta…
